Abstract

The utility model relates to a telescopic sport entertainment instrument: a telescopic hanging device, comprising rubber pads 1, 8 and cross bars 2, 7; one end of each cross bar is respectively sheathed in the rubber pads. The telescopic hanging device is characterized in that a telescopic adjusting mechanism between the two cross bars comprises a double-thread sleeve barrel 3 connected with the cross bars via threads. The utility model simultaneously parts or collects the two cross bars connected to the sleeve barrel 3 via double threads through the rotation of the sleeve barrel 3, and has rapid realization and symmetric extension or shrinkage. With homogeneous stress, simple structure, easy use and long life time, the telescopic hanging device is an ideal sport entertainment instrument for households.

Description

Telescopic hanging device

The utility model relates to a kind of use movement entertainment apparatus, particularly a kind of telescopic motion, amusement apparatus more.

At present, teen-age main motion, amusement apparatus generally all is horizontal bars, swing etc., but because these apparatuses need support to fix, thereby operated by rotary motion is at sports ground, ground such as shop, major part does not have condition to use this device per capita, a kind of indoor exercise is disclosed in CN2098940U, it comprises a cross bar, cross bar is by bassoon, tubule and block rubber are formed, bassoon is placed on the tubule, between two pipes governor motion is arranged, and block rubber is positioned at the two ends of cross bar, between block rubber and bassoon or the tubule movable axis is arranged, not limited by the place though it uses, its weak point is a unreasonable structure, and the screw rod in the governor motion is stressed excessive, easily deformation, and complex manufacturing.

The purpose of this utility model designs a kind of simple in structure exactly, uses the place convertible, long service life, the easily telescopic suspension arrangement of producing.

The purpose of this utility model realizes by following structure: telescopic suspension arrangement, include a rubber blanket and an end and be enclosed within cross bar in the rubber blanket respectively, its principal character is: a telescopic adjustment mechanism is arranged between two cross bars, expansion regulating mechanism comprise one with two screw shells 3 of cross bar screwed connection; Turnbarrel during use makes two cross bars flexible to withstand metope or to take off suspension arrangement to both sides simultaneously.

The utility model compared with prior art has simple in structure, and the place is not limit during use, long service life, and advantages such as easy production are the desirable apparatuses of family's motion.

Description of drawings of the present utility model is as follows:

Fig. 1 is a structural representation of the present utility model;

Among the figure: 1, rubber blanket, 2, cross bar, 3, sleeve, 4, nut, 5, screw rod, 6, fixture, 7, cross bar, 8, rubber blanket, 9, metope, 10, metope.

The utility model will be further described below in conjunction with drawings and Examples:

As shown in Figure 1: the utility model includes rubber blanket 1,8 and an end and is enclosed within the cross bar 2,7 that closes in the rubber blanket respectively, it is characterized in that: between two cross bars, have an expansion regulating mechanism, expansion regulating mechanism comprise one with two screw shells 3 of cross bar screwed connection; Sleeve two ends inwall has left and right hand thread to cooperate with the external screw thread of two cross bars respectively; Also in the sleeve middle part have by the fixing two-flight screw 5 of fixture 6, the internal thread of two-flight screw and two cross bars screws, two yardarm inwalls can be consolidated a nut 4 that screws with two-flight screw, process to reduce the material of use of cross bar, also to make things convenient for.

Claims

1, a kind of telescopic suspension arrangement, include rubber blanket (1), (8) and an end and be enclosed within cross bar (2), (7) in the rubber blanket respectively, it is characterized in that: between two cross bars, have an expansion regulating mechanism, expansion regulating mechanism comprise one with two screw shells (3) of cross bar screwed connection.

2, suspension arrangement as claimed in claim 1 is characterized in that: sleeve two ends inwall has left and right hand thread to cooperate with the external screw thread of two cross bars respectively.
